본 발명은 세탁기의 헹굼코스 알고리즘(Algorithm)에 관한 것으로, 특히 최적의 시기에 헹굼작동을 끝낼 수 있도록 한 농도센서를 이용한 세탁기의 헹굼 방식에 관한 것이다.The present invention relates to a rinsing course algorithm (Algorithm) of the washing machine, and more particularly, to a rinsing method of the washing machine using a concentration sensor to finish the rinsing operation at the optimum time.

종래의 세탁기에 있어 헹굼코스 알고리즘은 제1도에 나타내었는데, 이 경우는 1조 자동의 경우를 나타내고 있으며, 좌측 중앙의 헹굼코스 선택에서 급수 및 표준코스인 경우에는 1차 헹굼 3분, 2차 헹굼 3분으로 모두 6분 동안 일괄적으로 헹굼을 한다.In the conventional washing machine, the rinsing course algorithm is shown in FIG. 1. In this case, the first rinse course is shown, and in the case of water supply and standard course in the rinse course selection in the left center, the first rinsing period is 3 minutes and the second time. Rinse all for 6 minutes in 3 minutes.

또한 헹굼코스 선택에서 알뜰코스에는 2차 헹굼 3분만을 하게 하는데, 이는 세탁기가 헹굼작동시 세탁조 내의 상황과는 관계없이 일정한 시간만큼 동작한다.In addition, in the selection of the rinse course, the second round rinse only takes three minutes, which is the washing machine operates for a predetermined time regardless of the situation in the washing tank during the rinsing operation.

그리고 제2도에서 점선으로 나타낸 것은 2조 자동세탁기의 알고리즘을 나타내고 있는데, 이는 1차 헹굼 3분, 2차 헹굼 3분 그리고 3차 헹굼 6분을 수행하여 헹굼동작을 종료하도록 되어 있다.And the dashed line in Figure 2 shows the algorithm of the automatic washing machine, which is to complete the rinsing operation by performing the first rinse three minutes, the second rinse three minutes and the third rinse six minutes.

상기와 같은 종래 세탁기의 헹굼코스 알고리즘에 있어서 1조 자동과 2조 자동세탁기의 헹굼코스가 일단 정해지면 헹굼이 잘되든 못되든간에 정해진 시간 동안 헹굼 작동을 하게 되므로, 헹굼코스를 잘못 선택한 경우나 또는 헹굼코스를 제대로 선택했어도 세탁물의 오염 정도나 세제량의 다소 정도 혹은 세탁물의 다소에 따라서 헹굼이 덜되서 끝날 수도 있고, 반대로 헹굼을 과다하게 하여 물과 전기를 낭비하게 되는 문제점이 있게 되었다.In the rinsing course algorithm of the conventional washing machine as described above, once the rinsing course of the first and second automatic washing machines is determined, the rinsing operation is performed for a predetermined time regardless of whether the rinsing is performed well or not, Even if you choose the rinse course properly, depending on the degree of contamination of the laundry or the amount of detergent or some of the laundry may be less rinsing, and conversely rinsing excessively there is a problem that waste water and electricity.

이에 따라 본 발명은 상기한 문제점을 개선시키기 위해 세탁기의 세탁조 내에 농도센서를 부착하고 센서회로를 별도로 구성하여 마이콤에 연결하도록 하므로써 최적의 시기에 헹굼동작을 끝낼 수 있도록 한 것으로, 이하 그의 기술 구성을 첨부된 도면에 따라 설명하면 다음과 같다.Accordingly, the present invention is to attach the concentration sensor in the washing tank of the washing machine in order to improve the above problems and to configure the sensor circuit to connect to the microcomputer to finish the rinsing operation at the optimum time, the following technical configuration When described according to the accompanying drawings as follows.

제3도는 본 발명에 따른 세탁기의 구성도를 나타낸 것으로, 세탁조(4) 내의 일측에 농도센서(1)를 설치하고 별도로 센서회로(2)를 구성하여 마이콤(3)과 연결시킨 구성으로, 미설명 부호 5는 펄슈에이터이다.3 is a configuration diagram of a washing machine according to the present invention, in which the concentration sensor 1 is installed on one side of the washing tank 4 and the sensor circuit 2 is configured to be connected to the microcomputer 3. Reference numeral 5 is a pulsator.

상기 센서회로(2)의 구성을 제4도에서 나타낸 바와 같이, IC와 저항(R1,R2) 및 콘덴서(C1)로 주파수를 만들어 트랜지스터(Q1,Q2)로 증폭하고, 기준저항(Rref)과 농도센서인 저항(Rsen)의 저항 차이로 콘덴서(C3)의 전압을 발생시켜서 마이콤(3)의 A/D 입력단에 인가하도록 한 구성이고, 상기 농도센서(1)의 값과 마이콤(3)에 의한 헹굼코스방식은 제5도에 나타낸 것과 같다.As shown in FIG. 4, the configuration of the sensor circuit 2 is made of IC, resistors R1 and R2 and capacitor C1, and amplified by transistors Q1 and Q2. The voltage of the capacitor C3 is generated by applying the difference of the resistance Rsen, which is a concentration sensor, to be applied to the A / D input terminal of the microcomputer 3, and is applied to the value of the concentration sensor 1 and the microcomputer 3. Rinsing course method is as shown in FIG.

상기 구성의 동작상태 및 작용효과를 첨부된 도면에 따라 설명하면 다음과 같다.The operation state and the effect of the configuration will be described with reference to the accompanying drawings.

먼제 제4도의 센서회로도에서 농도센서(1)인 저항(Rsen)의 값은 세탁조(4) 내의 세제량과 물의 오염도를 나타내는데, 이 값은 마이콤(3)에 인가되어 제5도의 헹굼 알고리즘을 실행하게 된다.In the sensor circuit diagram of FIG. 4, the value of the resistance Rsen, which is the concentration sensor 1, represents the amount of detergent in the washing tank 4 and the pollution degree of water, which is applied to the microcomputer 3 to execute the rinsing algorithm of FIG. do.

본 발명의 헹굼방식에 대한 설명을 제2도의 헹굼 시간표와 제5도의 동작 순서도를 보면서 설명하면, 먼저 헹굼 동작이 시작되면 알고리즘은 일단 세탁기가 헹굼 동작을 하는지를 판단하는데, 즉 헹굼코스에서 펄슈에이터(5)가 회전하는지를 알아내어 급수시와 배수시를 판단하여 프로그램의 진행을 조정하고, 그 다음에 알고리즘에서 변수 "I"는 헹굼코스의 차수를 나타내는데 변수 "I"가 3이면 3차 헹굼이 완료된 것으로 간주하여 헹굼 프로그램을 완료하게 하고, 3이 아니면 세탁조 내의 세제량과 오염농도를 마이콤(3)이 읽은 전압 S1, S2, S3를 처리하게 되는데, 즉 증류수는 S값이 최대치이고 오염이 심하게 된 물일수록 S값이 "0"에 수렴하게 된다.The description of the rinsing method of the present invention will be described with reference to the rinsing time chart of FIG. 2 and the operation flowchart of FIG. 5. First, when the rinsing operation is started, the algorithm determines whether the washing machine performs the rinsing operation, that is, the pulsator (the 5) to determine whether the water is rotated and judge the water supply and drainage time, and then adjust the progress of the program. Then, in the algorithm, the variable "I" represents the order of the rinsing course. The rinsing program is completed, and if it is not 3, the detergent amount and contamination concentration in the washing tank are treated with voltages S1, S2, and S3 read by the microcomputer 3, that is, distilled water has a maximum value of S and contaminate The more S value converges on "0".

상기에 따라 센서회로(2)에서 마이콤(3)은 S값을 1초 간격으로 3번 읽어서 그 값이 모두 같을 때[즉, 세탁조 내의 세제농도 변화가 더 이상 없을 때] 헹굼작용을 완료하게 된다.According to the above, in the sensor circuit 2, the microcomputer 3 reads the S values three times at 1 second intervals and completes the rinsing when the values are the same (that is, when the detergent concentration in the washing tank is no longer changed). .

제2도에서 헹굼이 시작되면 S값이 점점 낮아지다가 어느 순간부터 일정값에 수렴되는 것을 알 수 있는데, 이때에는 헹굼동작이 일단 세탁조(4) 내에서 포화상태이므로 더 이상의 헹굼을 위한 펄슈에이터(5)의 교반이 필요없게 된다.In FIG. 2, when the rinsing starts, the S value gradually decreases and then converges to a certain value from a certain moment. In this case, since the rinsing operation is saturated in the washing tank 4, the pulsator for further rinsing ( 5) no agitation is required.

그러므로 이 포화상태가 체크되면 다음번 헹굼을 위해 물을 새로 넣거나 다음 헹쿰을 하던지 헹굼코스를 끝내게 되어 제2도의 헹굼시간 비교표에서 보는 바와 같이 기존의 헹굼 방식보다 4분 30초가 절약되면서 같은 헹굼 효과를 얻게 된다.Therefore, if this saturation is checked, new water for the next rinsing or the next rinsing is finished, or the rinsing course is finished. As shown in the rinsing time comparison table of FIG. do.

따라서 본 발명에 따른 농도센서를 이용한 세탁기의 헹굼 방식은 이상의 설명에서와 같이, 세탁물의 다소나 투입세제량의 농도 대소나 오염 정도를 고려하지 않고서, 즉 헹굼코스의 선택없이 헹굼을 진행시켜도 세탁조 내의 오염상태가 농도센서에 의해 계속적으로 감지되므로 최적의 상태로 헹굼을 할 수 있어 전력 및 물의 소비를 방지시키며 헹굼 시간을 단축시키는 효과를 갖게 된다.Therefore, the rinsing method of the washing machine using the concentration sensor according to the present invention, as described in the above description, does not consider the degree of contamination or the degree of contamination of the laundry detergent amount, that is, even if the rinsing proceeds without selecting the rinsing course, the contamination in the washing tank. Since the condition is continuously detected by the concentration sensor, the rinsing can be performed in an optimal state, thereby preventing the consumption of power and water and reducing the rinsing time.
